�4�faer � To the Mayor and Members of the City Council June 29, 1993
Subject: VILLAGE CREEK WASTEWATER TREATMENT PLANT - INTERIM SLUDGE
DISPOSAL - CHANGE ORDER NO. 1
On May 4, 1993 (M&C C-13$12), the City Council authorized an engineering
contract for the preparation of a bid package for long-term biosolids
(sludge) disposal. Bids are scheduled for advertisement in August 1993, with
an anticipated award of contract(s) date in September 1993.
The proposed bid package will provide the City with the opportunity to begin
decommissioning the sludge drying beds and begin using the plant's sludge-
only landfill facility. Provisions will be made for dewatering and disposal
of up to 100% of the treatment plant's biosolid production. In addition, the
contract will allow the Water Department the option to dispose of up to 30%
of the dewatered biosolids with internal forces at the sludge-only landfill
site allowing the Water Department to meet the requirements of previously
accepted grant funds.
At the present time it is planned that the contract documents will be
prepared such that awards may be made to separate contractors for three
individual contracts as listed:
1. Project I will be for dewatering of biosolids.
2. Project II will be for the conditioning of dewatered biosolids (to meet
regulatory requirements) and disposal by land application for
beneficial use.
3. Project III will be an interim contract to dewater and dispose of
biosolids while facilities are constructed for Projects I and II.
Project II is designed to provide the current level of dewatering and
disposal services during the estimated eight months required to construct the
permanent dewatering and conditioning facilities required at the sludge-only
landfill.
In order to continue disposing of the biosolids until the three contracts are
awarded, the Water Department has requested a Change Order extension of the
current biosolids dewatering and disposal contract. This change order is
consistent with the established goal of conversion to a long-term sludge
disposal process and elimination of the stockpile of sludge in the drying
beds over the next five years. The unit price established for this Change
Order s su antially less than the existing contract cost.
